does cash enter your account when you sell an option on a future? I thought you just put up the marked to market while the broker will haircut your account for the risk margin, like with a future.
When a customer SELLS an option the proceeds of the transaction would become part of the cash balance of the account.
Yes. the net long and net short options affect your balance, not your equity. You can call me if you have other questions. You earn no interest with Lightspeed/Wedbush on those.
